are we all explaining the same phenomena but disagreeing with exactly how to characterize what is going on? It seems my explanation wasn’t so off from what Bruno said, but I see it also matching what you said.\n\nwhat am I missing.\n\n\nGene beat me to it. Yes we are all on the same page. Ic6 somehow missed your key words, i.e. "half", "share". Though as I commented on this also, the way you tried to explain it could be confusing or misleading, and now we can see at least one person did get confused. Bruno's words as quoted by you, are clearer, though his first paragraph is much preferred (just my opinion as an EE), and his second paragraph, while also clear, seemed overkilling it, therefor against the K-I-S-S principle. \n\nAgain, there is nothing wrong with the way you put it, but it could have been kept simpler and clearer such as Ic6's though I agreed with paulgyro's post about his tone, that is uncalled for.
